Two new metal-organic frameworks (MOFs), namely, three-dimensional poly[diaquabis{μ-1,4-bis[(2-methyl-1H-imidazol-1-yl)methyl]benzene}bis(μ-glutarato)dinickel(II)] monohydrate], {[Ni(CHO)(CHN)(HO)]·HO} or {[Ni(Glu)(1,4-mbix)(HO)]·HO}, (I), and two-dimensional poly[[{μ-1,4-bis[(2-methyl-1H-imidazol-1-yl)methyl]benzene}(μ-glutarato)zinc(II)] tetrahydrate], {[Zn(CHO)(CHN)]·4HO} or {[Zn(Glu)(1,4-mbix)]·4HO} (II), have been synthesized hydrothermally using glutarate (Glu) mixed with 1,4-bis[(2-methyl-1H-imidazol-1-yl)methyl]benzene (1,4-mbix), and characterized by single-crystal X-ray diffraction, IR and UV-Vis spectroscopy, powder X-ray diffraction, and thermogravimetric and photoluminescence analyses. Ni MOF (I) shows a 4-connected 3D framework with point symbol 6, but is not a typical dia network. Zn MOF (II) displays a two-dimensional 4-sql network with one-dimensional water chains penetrating the grids along the c direction. The solid-state photoluminescence analysis of (II) was performed at room temperature and the MOF exhibits highly selective sensing toward Fe and CrO ions in aqueous solution.
通过水热法合成了两种新型金属有机框架材料（MOF），即三维聚[二水双{μ-1,4-双[(2-甲基-1H-咪唑-1-基)甲基]苯}双(μ-戊二酸根)二镍(II)]一水合物，{[Ni(C₅H₄N₂)(C₁₂H₁₄N₂)(H₂O)₂]·H₂O} 或 {[Ni(Glu)(1,4-mbix)(H₂O)₂]·H₂O}，(I)，以及二维聚[[{μ-1,4-双[(2-甲基-1H-咪唑-1-基)甲基]苯}(μ-戊二酸根)锌(II)]四水合物，{[Zn(C₅H₄N₂)(C₁₂H₁₄N₂)]·4H₂O} 或 {[Zn(Glu)(1,4-mbix)]·4H₂O} (II)，使用戊二酸（Glu）与1,4-双[(2-甲基-1H-咪唑-1-基)甲基]苯（1,4-mbix）混合，通过单晶X射线衍射、红外和紫外可见光谱、粉末X射线衍射以及热重和光致发光分析对其进行了表征。镍金属有机框架材料（I）显示出具有点符号6的4连接三维框架，但不是典型的dia网络。锌金属有机框架材料（II）展示出二维4-sql网络，其中一维水链沿c方向穿透网格。在室温下对（II）进行了固态光致发光分析，该金属有机框架材料对水溶液中的Fe³⁺和Cr₂O₇²⁻离子表现出高度选择性传感。
